Abstract

Techniques for generating preamble sequences for OFDM and OFDMA communication systems based on CAZAC sequences (120) with desired properties of constant amplitudes (CA) and zero autocorrelation (ZAC). Such preamble sequences may be used for synchronization and identification of individual transmitters. For example the OFDMA symbol is constructed using a CAZAC sequence in the frequency-domain (160) and the resulting time-domain waveform is a near-CAZAC sequence (170).
